Rawls is definitely Seattle’s most proven running back considering he is entering his third season with the team. As Rotoworld pointed out, Lacy is both getting acclimated to a new team and coming off ankle surgery.

This is a situation to monitor throughout the preseason, as Prosise was once considered to compete for the starting spot, and Lacy could continue to get healthier and acclimate even more.

From a fantasy perspective, this is a tough situation. Expect Rawls and Lacy to carry the majority of the load, with Prosise being a great passing-down option.
